Hi, we encountered this error during installations of the SecureDrop
application, which uses Ubuntu 14.0.4.5 for its server-side OS. We put
out an advisory which you can find here: https://securedrop.org/news
/advisory-server-installation-failure-uefi-boot-mode/ -but basically
we're seeing the same error as described above.
I just tried an install using the new shim-signed package as follows:
1) installed Ubuntu 14.04.5 to servers
2) updated /etc/apt/sources.list to include the trusty-proposed repository
3) ran sudo apt-get update
Then I proceeded with the SecureDrop install, which failed at the same
task and with the same error as before:
---

This is Ansible output - the actual apt-get command that failed is:
apt-get -y -o "Dpkg::Options::=--force-confdef" -o "Dpkg::Options
::=--force-confold" install 'securedrop-keyring'
I also tried installing shim-signed directly on the server with the command:
sudo apt-get install shinm-signed/trusty-proposed
This failed with a similar error about the shim package being an unmet
dependency.
Unless I'm setting up the -proposed repo incorrectly, I don't believe
adding dpkg as a predependency fixes this bug.
